Yes, I have been buying duplicates (sometimes even triplicates for both alternate forms) so that I can open these to play and display. But, I've only been buying the Deluxe and Voyager class figures because I don't much care for the minatures.

By going after the figures I like and not being a completionist for the sake of gettting the whole line, I can buy doubles and triples even. I do agree with the point raised concerning what fun it would be if they were all MISB, so this is my compromise.

The Classics and Encore series being fairly recent and each release staggered, means I could do it this way. I'd rather just leave the Takara and Hasbro reissues as they are considering the volume, scarcity and price of the them now.
